UNITED STATES ELIAS BLANEY, OF MARBLEHEAD, MASSACHUSETTS.

Specification forming partof Letters Patent No. 118,185, dated August22, 1871.

To all whom it may concern:

Be it known that I, ELIAS BLANEY, of Marblehead, in the county of Essexand State of Massachusetts, have invented certain Improvements inMachines for Shaping the Soles of Shoes, of which the following is aspecication:

My invention has for its object the shaping of shoe-soles after they arepegged or sewed 5 and is designed to supersede the necessity of shapingby the hammer. Itbelongs to that class ofmachines in which a die orformer is depressed by a screw upon the sole, which is placed upon aniron last arranged beneath the former, suficient pressure being given toform the sole into proper shape; and my invention consists in anarrangement ofdevices by which the last carrying the shoe isreciprocated alternately under the former to be pressed, and out towardthe front of the machine for changing the shoes, and combining with thismovement an automatic method of raising and depressing the screw, thetwo movements corresponding with each other, so that the machine may beoperated by power rotating continuously in one direction.

The drawing represents, in Figure 1, a sectional elevation of mymachine. Fig. 2 is a sectional elevation showing the shipping apparatus.

Similar letters of reference indicate like parts in all the gures.

The frame of the machine A is substantially made of cast-iron. B is theplaten or bed, upon which the sliding socket C traverses between theguides D. The last E is fitted into the socket C. The sliding socket Cis reciprocated by means of the screw-shaft I, having aright-and-left-hand screw-thread cut on the same portion of the shaft.At each end of the termination of the screwthreads on the shaftF twomovable collars, e a, are placed to which is attached a sliding piece,o, having guide-slots in one end so arranged that the traversing fork owill be guided in a straight groove around the shaft when the slidingsocket is required to be stationary, and guiding the fork into theright-and-left-hand threads to move the socket out or in. The collars ac fit in a groove in the sliding guide b. Bymovingthis sliding guide thecollars, with their pieces c, are moved to their proper position to formthe straight groove aronn d the shaft or turn the fork into the threadsof the screw. The sliding guide b is moved by the operator to start themachine, and automatically by a spring, g, after the shoe is pressed.The traversing fork o is tted into a movable piece, n, which is held bya set-screw, allowing the sliding socket to be moved out or in, so thatdifferent-sized shoes may fit under the former. 0n the shaftF is placedthe drum G and driving-pulleys H II. Motion is communicated by beltsfrom the drum G to the clutch-pulleys I I on the shaft K. One of theclutch-pulleys is driven by an open belt and the other by a cross-belt.A clutch, L, is iitted on the shaft K, and as it is connected witheither ofthe pulleys I I the shaft K is revolved in opposite directions.A bevelgear, M, is placed o'n the shaft K and drives a bevel-gear, N,which is placed on the screw O, which it turns by means of a sliding keyin a spline in the screw O, the gear being held in place by a claspiitted into a groove in the hub. At the lower end of the screw O thefollower P is fastened, which is moved up or down by the screw O, andguided by the w. ys Q. A former, It, is placed on the followerP and isdepressed upon the shoe with sufficient power to shape the sole by meansof the screw 0. The surface ofthe former maybe nickel-plated to preventthe oxidation of the iron and soiling the leather. The clutch L is madeto connect either pulley I I by means of a sliding fork, S, which isoperated by the attendant by a lever, to engage with the pulley drivenby the cross-belt. This gives a rotary motion to the shaft andbevel-gears, which turn the screw to depress the follower and former.The arm T is fastened to the follower, and as it is depressed a slide,U, is forced outward by means of a pin working in the inclined slot Wand striking against a weighted lever, Z, moving it just beyond itscenter of gravity, so that it falls over, :and its lower end, strikingon a pin in the slide a, throws the clutch into the pulley driven by thestraight belt just as the requisite pressure is given to the sole,thereby reversing the screw and raising the follower. The arm T extendsfrom the follower through the platen, by which it is guided, and carriesa movable catch, which, as it rises, trips the latch-catch Y, whichholds the sliding guide in place, throwing thc fork o into thescrew-thread and moving the shoe out to the iront of the machine.

As the screw O raises the arm T the inclined slotWmoves back the slideU, a pin on this slide the clutch midway between the pulleys I I,stoppin g the rotation of the shaft K while another shoe is being'placed on the last. The han d-lever is then moved by the operator, whichthrows the clutch Linto the pulley driven by the cross-belt at the sametime it moves the slide U to throw the fork o into the screw on thescrew-shaft F.

The screw on the screw-shaft F may be dispensed with, and the slidingsocket moved by hand.

I claim as my inventionl. In a machine for shaping the soles of shoes,the devices shown and set forth, by which the last is reeiprocatedalternately under the former and out toward the front of the machine,substanti al ly in the 1n aimer and for the purpose described. v

2. lThe combination of the screw-shaft F with the clutchL and pulleys II, operating in the manner substantially as and for the purpose specied.

3. In a machine for shaping1 the soles of shoes, the sliding piece c,for the purpose of guiding the traversing fork o, substantially as setforth.

4. The sliding socket C, made adjustable by means of the movable piecen, for the purpose set forth.
